WebApr 14, 2024 · Room-temperature superconductivity is a “rarefied state of matter in which electrical resistance in a material drops to zero while its electrical and magnetic capacity vastly expands.” Superconductivity has been observed previously, but only under cryogenic temperatures and phenomenally high pressures. Room-temperature … Superconductivity is a set of physical properties observed in certain materials where electrical resistance vanishes and magnetic flux fields are expelled from the material. Any material exhibiting these properties is a superconductor. Unlike an ordinary metallic conductor, whose resistance decreases gradually … See more There are many criteria by which superconductors are classified.
